I'll save it on 2.5.22 if it happens. Well I dunno, Randy. Works fine here, on aic7xxx SCSI and hpt366 IDE. >>From your trace it would seem that writeout completion has not occurred against one or more pages. Could be that the device driver lost an interrupt, or it failed to deliver completion for one or more BIO segments, or something screwed up at the VFS level. I am (of course ;)) disinclined to believe the latter, mainly because of the amount of testing I do here. Eight-hour Cerberus runs on quad CPU, five IDE disks and six SCSI disks all chugging along, no probs. Is it reproducible? Are you able to try it on a different machine? On other disks in the same machine? -
